wnrenme momma WITH AUTOMATIC mmcnrrne on PRINTING nn'vrcn Application filed June 1,

To all whom it may concern:

Be it lmown that we, PAUL SEITZ and A.

KRAMER, both citizens of Germany, residing at Kreuznach, Germany, have invented certain new and useful Improvements in Weighing Machines with Automatic Indicating or Printing Devices, of :which the following is a specification. V

This invention relates to weighing machines havin an automatic indicating or printing dev1ce which is arranged independently of the setting device for the weighing machine and is" tion after the setting of the weighing machine has been effected by the insertion of a coin or other manipulation. In the known weighing machines of this character the setting device of the weighing machine is braked as soon as it has oscillated into the weighing position and then turns a typewheel in accordance with the setting device, mostly by complicated mechanism, whereupon the printing. device is brought into operation; By the present invention the transmission of the movement to the indicating or printing device is considerably simplified and thus the weighing machine is rendered more certain in operation and caused to operate more rapidly.

According to the invention the setting device for the weighing machine comprises a pivoted sector adapted to be moved about its ivot into difierent positions according to t e load weighed, and this sector comprises a number of concentrically arranged segments which are radnated on their peripheral edges according to difierent de-" nominations of weight, for example three segments may be used graduated according 'to units and fractions thereof, tens and hundreds of units of weight respectively.

Each segment co-ope'rates with a corresponding movable key and the keys control the indicating or printing device. Whenthe keys are moved into engagement with their segments theirpositions are adjusted in the paths of and relatively to the numeral or only set. in opera- .type wheels or sectors of theprinting device so that the adjustments or movements of these wheels or sectors into their indicat-.. I

' medium of intermediate levers g, p voted ing or printing positions are determined by the keys. The aduations on the segments may be in the rin" of steps and it 18 preferred to rovide the segments for the tens and hun reds with graduations of such form, but for the units 01' fractions thereof 1922. Serial No. 565,247.

it is preferred to provide the stepson the.

corresponding key and to provide the units segment; with equally spaced projections.

The invention also comprises mechanism for releasing the keys, and for operating the indicating and printing device after the setting-0f the keys.

In the drawings: I Figure 1 is a front elevation of one form of automatic printing device for a weighing machine, and its controlling mechanism, ac-

cording to the invention. Figure 2 is a side elevation of the nu meral or type wheels or sectors.

Figure 3 shows the three keys detached and inside view. A

Figs. 4 and 5' are vertical sectional views taken at right angles to each other, Fig. 4 showing the segments a, 0 and d in section.

. In the form of the invention illustrated a sector 1 is rotatably mounted on an arbor b. It is operatively connected to the foot-board or weighing platform by the weighing mechanism in such a manner well known in the art. that when the foot-board is loaded it moves about the arbor 6 into the weighing position, for example in the direction of the arrow 0; in Figure 1. The right hand end of the sector corresponds to thezero load, whilst the left hand end corresponds to the maximum load.

The sector 1 has three concentric segments a, c, d. The peripheral edge of the segment edge of the segment d is graduated by steps corresponding to hundreds. of units of weight denominations' a After the sectors has been moved or set I by the load in the weighing position, en-

tirely independently of the indicating or printing device, a vertically guided rod 7 is raised. The "rod f ma be operated manually or by 00in free mechanism of any suitable type well known in the art. 3 When this occursa tappet h on the rod releases three keys I, m, and n, through the at so that the keys are te move downwardly under'the action of sprm and bear with their lower ends respectively on the segments a, c, and d The ke shown right at the back in Elgure 1, w eh corresponds to the first decimal position (the units), is itself provided with gradu-' ated steps a, by means of which it bearsupon one of the tooth-like rearwardly entending projections 72:.

Three type sectors p are pivoted on a pm t held in a'slotted bearing u by sprmgs v only one of which is to be seen in Figure 1.

1, m, n, are situated in the paths of the type sectors p which have projections 0 for engagement withthe u per ends of the keys. The 'keys therefore or indicating positions of the type sectors. Thus, after the keys Z, m, n, have been released and have engaged with the sector a and segments ad, the type sectors p fol low the movements of the keys and are thus set to the position for printing.

As soon as this has occurred the tappet h on the rod 7, strikes a lever i which 15 pivoted at i. The lever i in turn depresses the adjacent end .of a lever a pivoted at i and havin a tooth i which engages in notches 31 m the type sectors p so that the latter are raised against the action of the springs 0 towards the and against theweighmg 'card, delivered by the platen or carrier 9, so as to print thereon the weight of the load. The type sectors are then released for the next weighby a suitable crank or the like.

. being omitted.

not. follow the decima .also, the key n'may be graduated for fracin o eration. 4 g P The inventlon, 1s not applicable solely to weighing machines for people, but can also be applied to weighing machines for other purposes, such as for weighing parcels and the like. The insertion ,of .acoin, which operates the rod f and thus the keys Z, m, n, and the printing ,device may "be replaced The invention is also applicable toweighi ng inachines, which'do not print, but which indicate the weight, the type sectors pbeing then merely indicators and the platen g The weighing machine can also be arranged for weighing 0 erations which do system. Further,

tions of whole units of weight.

We claim;

1. Indicating or printing mechanism for V eterminethe printing laten or carrier 9 a weighing machine, comprising an pscillatory sector-having a plurality of segments,

saidsegments being graduated according to different denominations of weight, a plurality of movable indicating or printing elements, a plurality of keys, means for moving said keys into engagement with said sector 1 and segments after said sector has been moved by the load to be weighed, and means for moving said indicating or printing eletory sector having one segment provided with projections graduated ac cording to units of, weight, two segments on said sector having steps graduated respectively according to tens, and hundreds of units of weight, a movable key graduated in steps according to fractions of units of weight and adapted to engage with'the projections on said units segment, other movable keys adapted to engage with the steps on said tens and hundreds segments, and a movable indicating on printing element corresponding to each key and adapted to be controlled in its movements by said key, substantially as and for the purpose herei'nbefore set forth. 1 3. Printing mechanism for a weighing machine, comprising an oscillatory sector having a plurality of segments, said segments being graduated according to different denominations of weight, a set of movable printing elements, a set of movable keys for I arresting and thereby determining the printing positions of said printing elements, means for moving said keys into engagement with the said segments, after said sector has been movedby the load to be weighed, for the purpose of adjusting the. positions of said keys relatively, to said printing [elements, a printing platen, and means for moving .said printing elements, relatively to said platen after they have been arrested by said keys, substantially as and for the purpose hereinbefore set forth.
